METHOD AND DEVICE FOR SENDING SIGNAL, METHOD AND DEVICE FOR RECEIVING SIGNAL, AND METHOD AND DEVICE FOR DETERMINING RESOURCE

摘要

A signal sending method, a signal receiving method, a resource determining method, and a device are provided, to improve accuracy of a power headroom that is of a terminal device and that is determined by a network device. A signal sending method includes: generating a MAC CE, where the MAC CE is used to indicate a power headroom in a first power headroom set or a power headroom in a second power headroom set; and if the MAC CE is used to indicate the power headroom in the first power headroom set, the MAC CE includes a first bit field and a second bit field, the first bit field is a reserved bit field, and the second bit field is used to indicate the power headroom in the first power headroom set; or if the MAC CE is used to indicate the power headroom in the second power headroom set, the MAC CE includes a third bit field, the third bit field is used to indicate the power headroom in the second power headroom set, and the third bit field includes a bit of the first bit field and a bit of the second bit field; and sending the MAC CE to a network device.
